重庆地面气温年极大值渐近分布的拟合试验

Comparison between fitting results of four distribution functions and asymptotic distribution of the yearly maximum surface temperature over Chongqing

利用重庆1951-1996年间地面气温年极大值的记录,分别用韦伯分布、耿贝尔分布、皮尔逊Ⅲ型分布和对数正态分布进行拟合试验,通过统计推断比较,得出重庆地面气温年极大值遵循的渐进分布为韦伯分布和耿贝尔分布。

The Webull, the Gumbell, the Pearson III and the logarithmic normal distribution functions are used to fit the asymptotic distribution of the yearly maximum surfacr temperature over Chongqing area between 1951 and 1996. The result shows that the Weibull and the Gumbell distributions are better ones.
